/**
 * This example illustrates a common usage of the DrawerLayout widget in the
 * Android support library.
 * <p/>
 * <p>
 * When a navigation (left) drawer is present, the host activity should detect
 * presses of the action bar's Up affordance as a signal to open and close the
 * navigation drawer. The ActionBarDrawerToggle facilitates this behavior. Items
 * within the drawer should fall into one of two categories:
 * </p>
 * <p/>
 * <ul>
 * <li><strong>View switches</strong>. A view switch follows the same basic
 * policies as list or tab navigation in that a view switch does not create
 * navigation history. This pattern should only be used at the root activity of
 * a task, leaving some form of Up navigation active for activities further down
 * the navigation hierarchy.</li>
 * <li><strong>Selective Up</strong>. The drawer allows the user to choose an
 * alternate parent for Up navigation. This allows a user to jump across an
 * app's navigation hierarchy at will. The application should treat this as it
 * treats Up navigation from a different task, replacing the current task stack
 * using TaskStackBuilder or similar. This is the only form of navigation drawer
 * that should be used outside of the root activity of a task.</li>
 * </ul>
 * <p/>
 * <p>
 * Right side drawers should be used for actions, not navigation. This follows
 * the pattern established by the Action Bar that navigation should be to the
 * left and actions to the right. An action should be an operation performed on
 * the current contents of the window, for example enabling or disabling a data
 * overlay on top of the current content.
 * </p>
